SPECIFICATION forming part of Letters Patent No. 734,449, dated July 21, 1903.

Applioationfiled April 22,1902. Serial No. 104,123. (No model.) I

To all whom it may concern:

Be it known that I, JOHN R. VAN WORMER, a citizen of the United States, and a resident of Atlanta, in the county of Fulton and State of Georgia, have invented a new and Improved Lock for Collapsible Boxes, of which the fol lowing is a full, clear, and exact description.

This invention relates to a means for fastening together the parts of collapsible boxes formed of paper or other analogous material. It is particularly adapted for use and is here shown in connection with the nestable paper box patented by me August 6, 1901, No. 680,186.

This specification is a specific description of one form of the invention, while the claims are definitions of the actual scope thereof.

Reference is to be had to the accompanying drawings, forming a part of this specification, in which similar characters of reference indicate corresponding parts in all the views.

Figure 1 is a perspective view of a box in the position which it assumes at the beginning of the collapsing movement. Fig. 2 is a plan View of the box in the same position. Fig. 8 is a horizontal section of the box. Fig. 4 is a detail section of a lock employed, and Fig. 5 is a plan View of the blank from which the box is formed.

The box itself being the same as that shown in my prior patent need not be here described, except to say that d represents its bottom, e its unbroken sides, and Ct, b, and c the flaps at opposite sides of the box and to lock which together constitutes the object of the present invention. When the box is standing, the flaps a lie inside, the flaps 0 outside, and the flaps I) lie between the flaps a and c. i i

The lock may be made to connect two or more flaps. According to, the construction shown, the flaps b and care connected by two locks, while only one of these locks extends to the flap 0t. In forming the lock one of the flaps (the'flap o) in the drawings is cut to form a'tongue c. This tongue is-bent back upon itself to give it the form shown best in Figs. 3 and 4. The other flap or flaps,

as the case may be, are cut to form slits, which are preferably angular in form, producing short tongues 12 and a. These cuts are so located that when the flaps are folded together to form the standing box the tongue 0 will be in position to enter the cuts inthe other flaps. (See Figs. 3 and 4.) When thus arranged, the doubled portion of the tongue 0 projects past the tongues o. and b and looks against the walls of the cuts in the flaps a. and b. The single part or tail end, so to speak, of the flap 0 projects outward from the box in position to be grasped for the purpose of engagingordisengagingthe flap. This construction securely fastens the parts together, yet in such a manner as to admit of their easy disconnection. The double tongue 0 is not only of great strength, but it furnishes a projecting tail, which greatly facilitates manipulation of the part in question. The short tongues o. and b press against the tongue 0 and keep it firmly in active position, preventing it from bending back and thus tearing out of place.

Having thus described my invention, I

claim as new and desire to secure by Letters 'Patent 1. The combination of two parts, one of which has a cut therein, and the other of which has a tongue doubled or bent upon itself and entered into the cut, to connect the two parts together the free end of the tongue projecting outward to form a finger-hold.

2. The combination of two parts, one of which is cut to form a relatively short tongue, and the other of which is cut to form a relatively long tongue doubled or bent upon itself and projected into the cut in the first part, the said short tongue lying yieldingly against the other tongue.

In testimony whereof =I have signed my name to this specification in'the presence of 0 two subscribing witnesses.

J. T. MORELAND; I J. FRANK BECK.
